• Question 112:

  Interface FastEthernet0/1 is configured as a trunk interface that allows all VLANs. This command is configured globally:

  monitor session 2 filter vlan 1 - 8, 39, 52

  What is the result of the implemented command?

  A. All VLAN traffic is sent to the SPAN destination interface.
  B. Traffic from VLAN 4 is not sent to the SPAN destination interface.
  C. Filtering a trunked SPAN port effectively disables SPAN operations for all VLANs.
  D. The trunk's native VLAN must be changed to something other than VLAN 1.
  E. Traffic from VLANs 1 to 8, 39, and 52 is replicated to the SPAN destination port.
  E. Traffic from VLANs 1 to 8, 39, and 52 is replicated to the SPAN destination port.

• Question 113:

  A network engineer must improve bandwidth and resource utilization on the switches by stopping the inefficient flooding of frames on trunk ports where the frames are not needed. Which Cisco IOS feature can be used to achieve this task?

  A. VTP pruning
  B. access list
  C. switchport trunk allowed VLAN
  D. VLAN access-map
  A. VTP pruning

• Question 114:

  What happens on a Cisco switch that runs Cisco IOS when an RSTP-configured switch receives 802.1d BPDU?

  A. 802.1d does not understand RSTP BPDUs because they are different versions, but when a RSTP switch receives an 802.1d BPDU, it responds with an 802.1d BPDU and eventually the two switches run 802.1d to communicate.
  B. 802.1d understands RSTP BPDUs because they are the same version, but when a RSTP switch receives a 802.1d BPDU, it responds with a 802.1d BPDU and eventually the two switches run 802.1d to communicate.
  C. 802.1d does not understand RSTP BPDUs because they are different versions, but when a RSTP switch receives a 802.1d BPDU, it does not respond with a 802.1d BPDU.
  D. 802.1d understands RSTP BPDUs because they are the same version, but when a RSTP switch receives a 802.1d BPDU, it does not respond with a 802.1d BPDU and eventually the two switches run 802.1d to communicate.
  A. 802.1d does not understand RSTP BPDUs because they are different versions, but when a RSTP switch receives an 802.1d BPDU, it responds with an 802.1d BPDU and eventually the two switches run 802.1d to communicate.

  D. source MAC address and destination MAC address

• Question 116:

  Which statement about the MAC address sticky entries in the switch when the copy run start command is entered is true?

  A. A sticky MAC address is retained when the switch reboots.
  B. A sticky MAC address can be a unicast or multicast address.
  C. A sticky MAC address is lost when the switch reboots.
  D. A sticky MAC address ages out of the MAC address table after 600 seconds.
  A. A sticky MAC address is retained when the switch reboots.

• Question 117:

  You have been asked to install and configure a new switch in a customer network. Use the console access to the existing and new switches to configure and verify correct device configuration.

  

  You are connecting the New_Switch to the LAN topology; the switch has been partially configured and you need to complete the rest of configuration to enable PC1 communication with PC2. Which of the configuration is correct?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  E. Option E
  D. Option D

• Question 118:

  DHCP snooping and IP Source Guard have been configured on a switch that connects to several client workstations. The IP address of one of the workstations does not match any entries found in the DHCP binding database. Which statement describes the outcome of this scenario?

  A. Packets from the workstation will be rate limited according to the default values set on the switch.
  B. The interface that is connected to the workstation in question will be put into the errdisabled state.
  C. Traffic will pass accordingly after the new IP address is populated into the binding database.
  D. The packets originating from the workstation are assumed to be spoofed and will be discarded.
  D. The packets originating from the workstation are assumed to be spoofed and will be discarded.

• Question 119:

  After port security is deployed throughout an enterprise campus, the network team has been overwhelmed with port reset requests. They decide to configure the network to automate the process of re-enabling user ports. Which command accomplishes this task?

  A. switch(config)# errdisable recovery interval 180
  B. switch(config)# errdisable recovery cause psecure-violation
  C. switch(config)# switchport port-security protect
  D. switch(config)# switchport port-security aging type inactivity
  E. switch(config)# errdisable recovery cause security-violation
  B. switch(config)# errdisable recovery cause psecure-violation
